1 Claim.

This invention relates to rotary holders for sticks such as lipsticks, that is to say to holders of the kind in which the stick is projected from the holder and withdrawn into it again by rotary motion. It relates particularly to rotary holders of the type that is characterized by a long slender appearance. Such holders can be used with cosmetic sticks (including medicinal) of various kinds as will be apparent. At present they are used principally for lipsticks however. Accordingly for brevity I shall refer to lipstick holders substantially only hereafter.

Heretofore various forms of construction have been proposed for lipstick holders. Speaking generally, the present invention provides a holder having mechanism for projecting and retracting the stick that is peculiarly well suited for lipstick holders of the type indicated, and such a construction that the stick cannot be projected While the cap is in place thereby avoiding accidental and (careless crushing of the end of the stick against the end of the cap when the latter is in place and smearing the interior of the cap with Amaterial of the stick.

The accompanying drawings show a preferred form of the invention. Fig. l is a perspective of the holder with its cap in place. Fig. 2 is a longitudinal section of the same holder, also with the cap in place. Fig. 3 is a similar section but drawn to 4a larger scale and with the cap omitted. Figs. 4 and 5 are sectional views on the lines IV-IV and V-V respectively of Fig. 3.

Externally the lipstick holder illustrated consists of a tubular body shell I and a tubular base shell 2. The body shell I may be circular in cross-section (Fig. 4) preferably at least a portion of the base shell 2 is non-circular in crosssection, and may be polygonal (Fig. 5), for reasons appearing below. A cap 3, which can be of substantially any desired shape in cross-sectionl is provided to pass over the body shell I to close its open end 4 when the stick is retracted into the body shell I (Fig. l). Especially in order that the external diameters of the base shell and the cap may be about alike and thus the two line up well for appearance sake as shown in Fig. 1, I

prefer to make the base shell of a tubular seating portion or shell 5 and a bottom portion or shell 6 of somewhat larger diameter as will be understood from Figs. l and 2. The portion 6 can be called an extension, since in effect this latter portion 6 extends the base shell for some` distance from its junction with the body shell I.

Preferably 5 and E are two separate pieces, and f in such cases one end of the seating portion 5 (Cl'. 20G-56) 2 sets into one end of the extension 6 as shown, and the two are fastened together suiciently firmly lengthwise of the holder (frictionally or otherwise) to prevent the separation of the two under normal usage; the two may or may not be fastened together non-rotatably. One end of the body shell I is set into one end of the base shell 2, e. g. into the seating portion 5 of the base shell, and is mounted in it rotatably; for example. the two may be provided with complementary circumferential beads 9 and I0 to prevent Withdrawal of body shell I from the base shell but permit the body I to rotate within the base shell freely. The open end of the cap 3 is arranged to extend down over the end ofthe base shell `2. e. g. over the seating portion 5 of the base shell, and engage the same, say frictonally, suiliciently firmly to be held in place by the base shell (Figs. 1 and 2). The internal diameter of the cap-3 is so much greater than the external diameter of the body shell I that the cap is out of contact with the body shell I when seated on theubase shell (Fig. 2).

The elevator Il which carries the stick', vis reciprocable in the body shell I, toward and from open end 4 of the shell, so as to project the stick from the body shell for use and retract it into the shell again for protection. The elevator is reciprocated by a rotary type of actuator extending to the elevator from within the base shell 2 and responsive, directly or indirectly, to the relative rotation between the body shell I and the base shell 2. By rotary type of actuator, it will be understood of course that I refer to devices for converting from rotary to rectilinr motion, e. g. cam-slot-and-pin, threaded-bolt-and-nut, etc. Preferably the actuator is in the form of a threaded bar I2 fastened at one end to the elevator II and passing through and meshing with va nut I4 iixed to the body shell I, and at its other end fastened non-rotatably to the base shell 2 but in such a manner that the bar can move lengthwise with respect to the base shell 2. To the latter end a portion of the tubular base shell Z may be made non-circular in crosssection, internally, as before mentioned, a guide member I5 provided in this portion of the base shell, small enough to slide therein but also so non-circular as to be locked against rotation with respect to the base shell, and the lower end of the bar I2 may be fastened non-rotatably to this -guide member; for example, the interior of this actuator may be a twisted ilat bar as shown. In such a case the nut I4 may be merely a diaphragm with a rectangular hole for the passage of the bar through it as shown and as will be understood. In such a case particularly the nut I4 may be an integral end wall of the body shell I as shown. In the alternative however a conventionally threaded round bar, or aat bar notched at its edges appropriately to act as `a screw, etc., may be substituted for the twisted at bar I2 shown.

'I'he operation of the holder is rather evident. When the cap 3 has been removed, the elevator can be raised to project the lipstick from the end I4 of the holder for use, byv holding the body shell I by the fingers of one hand and rotating the base shell 2 with the fingers of the other hand. This action rotates the guide I5 and the latter rotates the bar I2 in the nut I4, with the result that the bar I2 moves lengthwise in the nut and accordingly. moves the elevator II to projectits lipstick from 4. Relative rotation of the two shells in the-opposite direction will returnfthe stick to within the body shell again. The.. ability ofthe guide I5Y to slide in the base shell permits the lengthwise movements of the threaded bar of course. When the cap 3 is in place on the seat portionS of the base shell, itcovers the body shell I completely of course. and also is entirely out of contact with the body shell because of the difference between their diameters. As a result the body shell I is wholly inaccessible for turning relative to the base shell 2, and accordingly the elevator cannot be reciprocated to project the lipstick from the end 4 whilel the cap 3 is inrplace.

It will be understood that our invention is not limited to the details of construction and operation described above and shown in the drawings, except as appears hereafter in the claim.

We claim:

Ina holder for sticks, a single unitary tube open at one end forming a bottom shell, said tubebeing non-circular for at least a portion of its length, a single unitary tube open at both ends seated within the first mentioned tube and projecting from said open end thereof, said two tubes being xed against both longitudinal and rotary mvement with respect to each other and the external diameter of the rst mentioned tube being greater than the external diameter of the second mentioned tube so that the first mentioned tube provides a shoulder around the exterior of the second mentioned tube, a third unitary tube open at one end and at its other end seated within the second mentioned tube and xed against longitudinal movement with respect thereto but being rotatable with respect to said second mentioned tube, an elevator within said third tube, said third tube serving as a guide for the elevator as the elevator reciprocates within said third tube, a threaded bar projecting from said elevator, through the second mentioned tube and into the first mentioned tube, a guide member within said rst mentioned tube, correspondingly non-circular, and reciproca-ble therein, attached to vsaid threaded bar, a spiral connection being provided between said third tube and said threaded bar, and a cap to set over and on said second mentioned tube and against said shoulder, the internal diameter of said cap being greater than the external diameter of said third tube.
